Not worth the $12 you'll likely spend on a baked good and coffee. I've been to every Amelie's location in Charlotte and the only one that delivers quality is the NoDa Amelie's.
After dinner yesterday we went to the Park Road location. Their dessert case isn't as robust as others but that didn't bother me because whatever I taste I care about the quality. We ordered two macaroons, a petite four, and slice of cake. The cake was good, the macaroons were okay, but my hazelnut petite four truly tasted like it had freezer burn (kind of like if cardboard had a taste).
To me, if I pay $2.15 for a dessert it should be worth it's wait because baking is such a unique skill.
The atmosphere was fine, it's an open floor plan and a bit noisey but you can comfortably have a conversation. I wouldn't be able to study at this location though or read a book.
